I'm not anti-cutting, I like the idea of keeping the truck as low as possible. I bought my Vit new and really didn't want to cut it.
I've been out and pulled my rear suspension and I have to put my hand up and admit to being wrong. I haven' t seen a kit for a Track/Kick with bumpstop extensions but you got me thinking and worrying a little.
My 3" Calmini kit has no bump stop extensions. I bought it used but I've looked at the pic on the Calmini site and at their description of whats included and theres no reference to any. Now I've taken some measurements and against the bumpstop there is around 13" of shock clearance and around 5" of spring clearance. Thats not good because the Calmini shocks are around 15" long compressed, looking back on this forum the stock shocks are 13" compressed so they have actually maxed out the travel. According to my calculations the Calmini spring fully compressed would be 6 1/2", I haven't got a stock spring handy to measure, Although I'm pretty sure that I've got one somewhere.
This means that I do need to extend the bumpstops, the shocks aren't an issue because the top mounts are being relocated anyway (longer shocks to go on) but the springs are going to sag if I leave the set up as it is. I'm going to repeat this exercise on the front suspension as well but I probably won't get to that for a couple of weeks. I'll post up what I find.
Its an important subject and I thank you for making me go back and investigate this. I wonder how other aftermarket suspension setups stack up. It certainly doesn't look good for those using spring spacers.
Edit: To be fair to Calmini I should have said that its possible that the rear spring could sag, given its length it would take a lot of weight to compress it that far.
The figures I gave above for the front strut lengths are correct as I have measured them previouslyyea, I just put teh pro comp shocks from boondox on that are supposed to be 0-2 inch lift and they definatly bottom out.. I need to extend my bump stops and lift it to make them work right. They also unseat when fully flexed (articulates much better)sounds like calmini shorted you bump stop extenders. I am not sure about the springs sagging if there is excessive up travel but I don't think it would take more weight to make them go up 8 inches than 2 or something unless they are progressive rate coils. a friend of mine has a grand cherokee with lift coils and coil spacers and stock pads. it has soo much flex and I don't think his coils have really sagged at all yet. I do see how it could be really hard on the coils to do that though, just not sure if it really is or not
I am seeing the point of a body lift though even with new bump stops cause my new shocks do max out upwards and when it's fully flexed it doesn't lose that much upper wheel travel like that. It only has like 2.5 inches of up travel tops right now so I really need to lift it and extend my bump stops. but my sayng the bump stops would likely take care of the tire clearance in many cases was probably not correct cause once the axle is all angled the tire still goes up high and my shocks are stopping it
yea, that's probably worded like crap but oh well. best of luck to you with your future mods you mentioned
